In this study, spherical-like polypyrrole nanoparticles with diameter smaller than 100 nm were synthesized via emulsion polymerization using FeCl3 as dopant and initiator simultaneously. Chemical structure of polypyrrole was confirmed with FTIR spectra. Furthermore, the morphology and the size of polypyrrole nanoparticles were investigated by SEM images. The structural order of samples was investigated using XRD analysis and the conductivity of samples was measured by four point probe method. In this work, effective factors on the conductivity of resulted polypyrrole including reaction temperature, initiator concentration and feeding strategy were investigated. In this study, without the use of complex equipment of synthesis or the use of different raw materials simply by optimizing the reaction conditions, a product with a conductivity of 8.5 S/cm was obtained. Moreover the aging effect on the conductivity of product was discussed.
